AI image models compared
Nano Banana vs Seedream v4
These two get compared constantly and they are not really rivals — they do different jobs. Seedream v4 is a generator: you describe a scene and it produces a photograph of it, with the best skin and light available here. Nano Banana is an editor: you give it an image and describe a change, and it makes that change while keeping the subject the same person.
The practical answer for most projects is both. Generate the first frame on Seedream, where photorealism is strongest, then move it to Nano Banana for every variation after that, where identity consistency is strongest. Trying to get a consistent character out of Seedream alone means re-rolling until faces happen to match, and trying to get Nano Banana to originate a photoreal scene from nothing wastes what it is for.
Choose Nano Banana if
- The same character or product must recur across images
- You are refining an image you already have
- You want to describe edits in plain language
Choose Seedream v4 if
- You are creating a scene from scratch
- Skin, light and photographic realism are the priority
- You need an exact pixel size or a very large canvas
